FISH-CAR.

Specification of Letters Patent.

Application filed August 21, 1914. Serial No. 857,960.

. ing the change of the water in which the capillary perforations 9 issuitably arranged fish'are originally placed.

The invention consists of automatic oiling means for apump and in meansfor preventing the oil from entering the water in the tanks with the airfrom the pump.-

\Vith these and other objects in view, the

invention consists in the above and other fea-r tures of construction,combination and arrangement of parts which will appear as thedescription proceeds, and will be finally pointed out in the appendedclaim.

The drawing accompanying the specification illustrates theinvention in aconcrete and preferred embodiment but it is to be understood that theinvention is capable of many changes and modifications without departurefrom the spirit and scope of the invention.

The invention is illustrated in: Figure 1 Which is a vertical sectiontaken through the car, and illustrates the air pump which is driven fromthe running-gear of the car. Fig. 2-is a fragmentary side view taken substantially on line 3-3 of Fig. 1, and shows one of the tanks in section.Fig. 3 isa fragmentary detail view, partly in section, of the pressureregulating means of the system.

Similar and like characters referred to in the following specificationdenote similar and like parts throughout the drawings.

.1 indicates the body of a car, or other vehicle having disposed andsuitably arranged thereon the fluid tanks 2. It is to be understood thatalthough the invention is here shown as a car equipment it may be usedin connection with boats or fish aquariums, or

the like where it'is desired to retain live.

fish in tanks of water.-

A piping 8 formed with a multiplicity of in each tank 2 below the waterlevel therein and is supplied with air from a suitable air supply 10-,which forces the air through the same. This piping 8 is connected to themain supply pipe 11-through the branch pipe 12 and the flexible tubeconnection 13, \VhlCll' latter immediately connects the branch pipe 12and the piping 8. Conven 1ently located in each of the branch pipes 12is a cut-off valve 14 for shutting off and regulating the flow of airpressure to each respective tank.

l A rotary pump 10 is provided for supplymg air to the tanks when thecar is in motion. This pump 10 may be of any suitable Patented Nov. 30,1915..

construction and is mounted upon the f spring bed 17 and is driven fromthe running-gear 18 of the car by the belt or chain 19.}. The pump isconnected with the'main pipe 11 through the branch tubes 20, the

reservoir 21 and the supply pipe 22. Suitp ably located in the supplypipe 22 is the cut-off valve 24 which governs communica- 75.

tion between the pump 10 and the main pipe 11. The reservoir 21 isadapted to contain a low level of oil 23 which is acted upon by the airressure therein and forced through 1 the nee 1e valve 24*, branch pipes25 to the pump, this provides automatic means for oiling the pump.Extending from substantially opposite sides of the rotary motor 10 are Tconnections 26 which are provided with the inlet ends 27 and the outletends 28 the latter having one of the branch tubes 20 connectedtherewith. Suitably located in the inlet and outlet ends 27 and 28 otthe T connections 26 are the check valves 29 and 30 which automaticallyoperate to feed air into one of the branch tubes 20, accord.-

ing to the direction of rotation of the motor. In other words, when thecar is traveling in one direction air is drawn in by the pump 10 throughone of the inlets 27 of one of the T connections 26 and is forced fromthe pump through the other Tconnection on the opposite side of the pump,through the flexible connection 20 to the reservoir 21. When the.direction of the car is reversed the check valves 29 and 30automa'tically select the inlet'and outlet ports of the pump.

- Whenthe pump is in motion and air pressure is forcedto the reservoir21 oil' is fed I to the pump, but since the tubes 20 are connected tothe reservoir 21 above the oil level,

the oil will drop to the bottom of the reservoir and will,not be carriedinto the water,

in the tanks. Between the reservoir 21 and the main pipe 11 there isprovided the bypass or trap 31 having a nipple 32 threaded. I

4 therein and-having suitable slots or perforations 33 formed thereinThe cap 34 is threaded upon the nipple 32 and is adapted to open andclose the perforations 33. It has been found that when the car istraveling at a high rate of speed the air from the motor 10 is of toohigh a pressure to be supplied to the tanks 2 and by the provision ofthe perforated nipple 32 and the cap 34: the pressure from the pump tothe main supply pipe 11 may be reduced The trap 31 a1so provides anadditional means for preventing the oil from the pump 10 from enteringinto the water in the tanks 2 and upon removal of the cap 34 of thenipple 32 the trap 31 may be drained of any oil that may settle therein.

Ina device of this character, when live fish are kept for the purpose offood, it is very essential that the reservoir 21 and the trap 31 beprovided for preventing the oil from being carried into the water in thetanks with the air and thus polluting the water.

What is claimed, is:

In a device of the class described, a fluid tank, an air pump, a pipeconnection between said air pump and tank for supplying air pressurethereto, a reservoir in said pipe connection, an automatic pump oilingmeans connected to the reservoir and completing, together with a sectionof said pipe connection, an oil circulation to prevent oil' from beingcarried into the tank, an auxiliary means between said tank andreservoir for trapping the oil carried in the air pressure from thereservoir, and means for regulating the air pressure throughout thesystem and providing an outlet for said auxiliary trapping means.
